What P0A92 means
P0A92 indicates that the generator of a hybrid system, the electric machine mainly used to convert engine power into electrical energy, does not reach the expected output, speed or torque. CARB requires manufacturers to describe how they monitor the generator so that faults preventing it from working are detected. FCA documents the code for the 2020 Jeep Compass and Renegade plug-in hybrids (bulletin 08-057-21): it appears together with drive motor phase current sensor codes, and the fix is a software update of the hybrid control processor and power inverter module. A turtle (limp home) lamp may accompany it. P0A90/P0A91 cover the drive motors; P0A3F and similar codes cover generator position sensing.
P0A92 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor0.5 to 8 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0A92
- MIL and hybrid system warning
- Limp home (turtle) lamp, reduced power
- Reduced charging of the high-voltage battery
Common causes of P0A92
- Most likelyHybrid controller or inverter software needing update (documented by FCA)
- PossibleInverter phase current sensing fault
- Less likelyInternal generator fault (winding, bearing, position sensor)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0A92 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| A | Area: hybrid propulsion. |
| 92 | The exact fault in that area. |
What to do next
- Note P0A92 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0A92
What does P0A92 mean?
P0A92 means "Hybrid Generator Performance". P0A92 indicates that the generator of a hybrid system, the electric machine mainly used to convert engine power into electrical energy, does not reach the expected output, speed or torque. It is a generic code, so it means the same on every make.
Is it safe to drive with P0A92?
Drive gently and only to a workshop. With P0A92 the car can go into limp mode (reduced power) to protect itself.
Will P0A92 fail an emissions test?
Yes, it can. P0A92 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0A92 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 8 hours of work. This is a job for a workshop.
Will P0A92 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
